Call stack Options.
The DRC-1 offers a call stack to store incoming idents. This menu facilitates how the calls are
handled within the DRC-1. Select [
menu
] to access the menu item, then, use the scroll
up/down to move through the options. When the desired option is opposite the chevron,
pressing [
menu
] will select the option, then, press [
clear
] twice to store and exit the menu
facility. The options are:-
Call Stack Disabled
. There is no call stack in use, and the received idents/status will
be displayed as they are received. The idents then will appear to go into a queue as if
the call stack is available, but this queue is only one call deep. Also, reception of
further idents will replace the ident waiting. To recall the ident from the one deep
queue, use the arrow keys as normal.
Discard Oldest Call.
The call stack length is sixteen calls. When the call stack is full,
selecting this option will remove the oldest call from the stack and replace it with the
one currently being decoded.
Refuse Call If Full.
The call stack length is sixteen calls. When the call stack is full no
further calls will be placed into the stack. ** also see logging printer. All these items
are programmed in the same way, press [
menu

up/down scroll keys until the desired item is opposite the chevron, then press [
menu

to select item, then [
clear
] twice to store selection and exit the menu system.
Leading Repeat Tone
A leading repeat tone is sometimes used to signal to other DRC units that this call is outgoing
and not incoming when the DRCs are connected to a common line. The available options are
on/off. Select [
menu
] to access this item then use the scroll up/down keys to see the selection
available. Press [
menu
] to select the desired option, then, press [
clear
] twice to exit the menu
system and implement the changes.
Circulating Calls.
This is a special signalling method used only with Simoco / Philips voting systems.
Alert Tone Default
Sets if alert tones are enabled after power up / reset.
Alert Tone Type
Sets intermittent or continuous tones for alert status.
Call Log Printer.
All selcall activity can be routed to the communications connector for connection to a logging
printer. This menu item permits the logging output to be switched on and off. It should be
noted that if this output is enabled, and the call stack is full, the logging output will continue
and thus provide a record of all calls received when the stack is full. Press [
menu
] to access
this item, then use the up/down scroll keys to indicate on or off. Press [
menu
] to make
selection, and press [
clear
] twice to store end exit.
